Abstract
Abstract An electronic endoscopic system comprises an endoscope having a solid-state element assembled to an end thereof, a memory for storing color correction data with respect to a reference color of sections to be obtained by dividing a chromaticity diagram plotted according to the color reproductivity of the solid-state imaging element, and a device for selectively addressing the color correction data stored in the memory.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
60 words
An electronic endoscopic system comprising: an endoscope means having an imaging element assembled to an end thereof; a memory means for storing color correction data with respect to a reference color, of respective sections obtained by dividing a chromaticity diagram plotted based on the imaging element; and means for selectively addressing the color correction data stored in said memory means.
Claim 2
Dependent Claim
60 words
An electronic endoscopic system comprising: an endoscope means having an imaging element assembled to an end thereof; a memory means for storing color correction data with respect to a reference color, of respective sections obtained by dividing a chromaticity diagram plotted based on the imaging element; and means for selectively addressing the color correction data stored in said memory means.
Claim 3
Dependent Claim
19 words
An electronic endoscopic system as claimed in claim 1, wherein said reference color is provided in a plural number.
Claim 4
Dependent Claim
30 words
An electronic endoscopic system as claimed in claim 1, wherein said endoscope means is used as an address for reading out the color correction data stored in said memory means.
Claim 5
Dependent Claim
27 words
An electronic endoscopic system as claimed in claim 1, wherein said memory means is provided with a memory circuit for storing at least one of said sections.
Claim 6
Dependent Claim
